摘要
提出了一种新型的单 /双开关正激式 (Forward)直流变换器的电路仿真平均模型。这种模型可通过输入参数的选择实现对Forward电路的电压控制 ,峰值及平均电流控制 ,以及对DCM -CCM工作方式的自动转换。这是一种实用的仿真模型 ,可方便地进行稳态和动态分析。在保证准确的基础上 ,大幅度地提高了仿真速度 ,较之用实际器件开关电路的仿真速度高 2～
A novel average model for single/double switches forward DC DC converters has been developed. With this model voltage control mode, peak current control mode and average current control mode can be easily realized by simply changing the parameters of the average model. This model also could automatically shift between continuous conduction mode (CCM) and discontinuous conduction mode (DCM). It can be used for static and dynamic circuit analysis. By using this proposed average model the simulation speed can be improved by 2～3 order in comparison with conventional switched model.
